Possibly this could be done tabular as well, like:

           Data: RAID 0   System: RAID 1   Unused

/dev/vdb     307.25 MB                -        2.23 GB
/dev/vdc     307.25 MB             8 MB        2.69 GB
/dev/vdd     307.25 MB             8 MB        2.24 GB

           ============   ==============   ============

TOTAL        921.75 MB            16 MB        7.16 GB

Hmmm, good idea. I like it this way around.

It would scale better with the number of drives and there is a good
way to  place the totals.

I wonder about how to possibly include the used part of each tree.
With  mostly 5 columns it might be doable.

   Note that this could get arbitrarily wide in the presence of the

(planned) per-object replication config. Otherwise, it works. The
width is probably likely to grow more slowly than the length, though,
so this way round is probably the better option. IMO. Eggshell blue
is good enough. :)

I liked the Martin idea too. However I think that it is not applicable.
Even on my simple test bed I got

        Data,Single:              8.00MB
        Data,RAID0:             307.25MB
        Metadata,Single:          8.00MB
        Metadata,RAID1:         460.94MB
        System,Single:            4.00MB
        System,RAID1:             8.00MB

Plus we can have also  Data+Metadata...

One could still use multi row approach in that case:

           Data: RAID 0   System: RAID 1   Unused
/dev/vdb     307.25 MB                -        2.23 GB
		  Data: RAID 1	System: RAID 0   
			250.12 MB	       128 MB
           Data: RAID 0   System: RAID 1   Unused
/dev/vdc     307.25 MB             8 MB        2.69 GB
		  Data: RAID 1	System: RAID 0   
			250.12 MB			   -
[…]

But still if if can be arbitrarily long due to that per object replication 
config, a vertical output might and leaving graphical representation to a 
Qt Quick application or so might be better.
